    We have assessed this requirement. We have no current plans for this to be implemented and so this requirement is being declined at this point. For Type 4 we recommend you use a Liberty JVMSERVER.

    Have you seen this performance Red Paper comparing JDBC Type 2 and Type 4 in a Liberty environment ? See http://www.redbooks.ibm.com/abstracts/redp5208.html?Open

    One of the conclusions is

    For the global transaction scope configurations used in this study, it was found that the type 2 JDBC driver delivered the best performance characteristics, in terms of total CPU cost, zIIP usage, and web request response times.


    So type 4 should not be seen as a means of reducing cpu time.
